Meet our spectacular Cogs! The barbed thread helps to hold the skin like a hook and when you pull the
thread to the desired direction, you can see the surprisingly lifting effect.
 
We call FC type as cutting type cog needle.
You can cut off the thread after lifting it to the direction you want to lift. It is perfect to have lifting effect.
 
We call FD type as non-cutting type cog needle.
You don't need to cut off the thread since all thread is inserted into the skin. It is good to have volume up effect
